ANVIL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 426,280, dated. April22, 1890.

Application filed December 2'7, 1889. Serial No- 335,158. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. KING, of Downievillc, in the county ofSierra and State of California, have invented anew and Improved AnvilAttachment, of which the following is a full, clear, and exactdescription.

My invention is adapted to be attached to an ordinary blacksmiths anvil;and the object of my invention is to provide means whereby metal may bequickly and easily bent and cut oif upon the anvil.

.lleretofore when a blacksmith has had oecasion to bend a piece of metalit has been the practice to take the metal in aheated condition to anordinary vise and bend it in the vise, or have an assistant hold abending-piece upon the anvil and bend the metal over that; but myinvention obviates this difficulty by providing means whereby theblacksmith may bend and cut off the metal upon the anvil without thehelp of an assistant.

To this end my invention consists in a swinging arm provided with a gripand actuated by a chain or cord connected with a treadle-lever andattached to the anvil-block, so that by dopressin g the lever the gripwill be swung upon the end of the anvil in position to hold a piece ofmetal thereon. This construction will be hereinafter fully described,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of an anvil and block provided with myinvention, with a portion of the anvil-block in section to show themanner in which the invention is at taohed, and with the grip andswinging arm depending from the anvil-block. Fig. 2 is a front elevationof the same, but showing a grip without a hardy and clasping the end ofthe anvil, ready for use. detail showing the manner in which theswinging arm is held and pivoted to the anvilblock, and Fig. t is anenlarged detail of the pivot end of the swinging arm.

The anvil A and anvil-block B are of the usual construction, except thatthe anvilblock is hollowed out upon each side near the bottom, so thatthe lever C, which is attached Fig. 3 is an enlarged thereto, will notproject beyond the sides of the anvil-block and interfere with theblacksmiths work.

The U-shapcd lever C is pivoted to the sides of the anvil-block B by thepin a, and is provided with a suitable treadle'b, so that it may beeasily actuated by the foot. of the blacksmith. A chain (Z is attachedby one end to the lever C and by the other end to the end of an arm D,pivoted in a bracket E, attached to the anvil-block.

The arm D is provided at its free end with a grip e, which is of arectangular shape and is large enough to clasp the end f of the anviland to admit a fair-sized strip or bar of metal between it and the faceof the anvil; and the other end of the arm is formed into a disk g,which is pivoted between the pro jecting sides of the bracket E by thebosses or strips g, and the disk is provided upon its periphery with agroove, as shown in Fig. 2, to receive the chain or cord d.

The bracket E is provided with flanges 9, having screw-holes therein, bymeans of which it is attached to the anvil block B. The bracket E isalso provided upon each side with a vertical slot j, enlarged andcircular at the upper end, which circular ends receive the bosses orstrips g by which the arm D is pivoted to the lug, and from the bosses 9project axially the pins h. The arm D will be capable of a verticalmovement in the bracket E a distance corresponding to the length of theslots 7'.

The strips 9 are attached to the sides of the disk g, or may be madeintegral with it and project therefrom so that they will enter the slotjof the bracket E and turn in the upper enlarged circular part of theslot. The strips are so attached to the disk that when the arm D is in avertical position and the treadle-lever C is depressed they will slideinto the lower part of the slotj and will be retained by the sides ofthe slot so that the arm D cannot be tipped down.

Springs 7e are attached to the anvil-block B and extend outwardly alongthe sides of the bracket E and underneath the ends of the pins 71.,which project from the bosses or strips g and press said pins and stripsto the top of the slot j of the bracket E, so that when the arm D is ina vertical position, with the grip e clasping the end f of the anv ii,the springs acting upon the pin 7?, strips g, and arm D will hold thegrip in an elevated position, as shown in Fig. 2, so that there will bea space between the top of the grip and the face of the anvil, in whichmetal may be inserted and held, as hereinafter described.

The chain 01 is attached to the lever 0 directly und erneath the bracketE, and the other end of the chain is attached to the disk g of the armD, near the inner side of the arm when it is in a vertical position, sothat when the arm is tipped down, as shown in Fig. 1, the chain d willbe wound nearly around the disk 9, as indicated by the dotted lines inthe same figure.

When the foot is placed upon the treadle Z), the lever O is depressed,the chain 0?! is tightened, and this, acting upon the disk turns thedisk upon the strips g in the enlarged part of the slot 3' and raisesthe arm D, so that the grip 6 will clasp the end f of the anvil with thegrip in an elevated position, with a space between the top of the gripand the face of the anvil. Byincreasing the pressure upon the treadle bthe pins h, which bear upon the springs lo, will depress the springs,the strips 9 will slide downwardly in the slots 7' of the lug E, and thearm D will drop vertically, thus bringing the grip e firmly upon anymetal which may be between the grip and the anvil, or, if there is nometal there, the grip will be forced down to a solid bearing upon theanvil, so that the hardy Z may be used in the usual manner. By removingthe pressure the springs will lift the'arm D'an'd grip e, and the actionmay be repeated as often as necessary.

To bend a piece of metal, the blacksmith places the end of the piece tobe bent between the face of the anvil and the grip 6, By increasing thepressure upon the treadle b the grip e will be forced down upon themetal, and it will be held as in a vise, so that the metal may be bentover the end of the anvil f by a few blows from the blacksmiths ham- Thegrip 6 may be provided at the top with a hardy Z, so that by forcing thetop of the grip 6 upon the face of the anvil A to make a solid bearing apiece of metal may be cut off upon the hardy Z in the usual manner.

This invention is especially valuable to the blacksmith infittinghorseshoes. By pressing upon the treadle b the grip e and hardy Zwill be thrown into position in the manner described for cutting theheels of the shoe, and by removing some of the pressure the springs 70will raise the grip 6, so that the shoe may be held between the grip andanvil and turned into the required shape.

WVhen the grip e or hardy l is not in use, the arm D is tipped down intothe position shown in Fig. 2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with an anvil and anvil-block, of avertically-swinging arm pivotally attached to the anvilblock, having atone end a grip adapted to clasp the end of the anvil, and means foractuating said arm, substantially as described, and for the purpose setforth.

2. The combination, with an anvil and anvil-block, of avertically-swinging arm pivotally attached to the anvil-block, having atone end a grip adapted to clasp the end of theanvil, and having theother end connected by a chain or cord with a suitable lever foractuating said arm, substantially as described, and for the purpose setforth.
